当使用Flink向ClickHouse批量持续写入数据时,遇到如下的错误信息: Caused by: java.sql.SQLException: Code: 241, e.displayText() = DB::Exception: Memory limit (total) exceeded: would use 6.86 GiB (attempt to allocate chunk of 4295130 bytes), maximum: 6.86 GiB (version 20.8.3.18) , server ...
Memory limit (total) exceeded: would use 6.86 GiB (attempt to allocate chunk of 4196472 bytes), maximum: 6.86 GiB:这说明查询已经超过最大内存限制,导致查询失败。可以通过参数max_memory_usage来进行设置,提高内存上限。类似的还有很多。Clickhouse提供了大量的参数配置,例如:一般常用的主要有以下几种:1...
之前,查询受到 max_memory_usage 设置(默认10GB)的限制,这提供了一个简单粗暴的限制。用户可以在单个查询上提高内存,但可能会影响其他用户使用。内存overcommit允许运行更多内存密集型的查询,只要存在足够的资源。当达到最大服务器内存限制(max_server_memory_usage)时,ClickHouse将确定哪些查询最超配,并尝试杀死...

ClickHouse服务端对所有查询线程都配有memory tracker,同一个查询下的所有线程tracker会汇报给一个memory tracker for query,再上层还是memory tracker for total。您可以根据情况采取如下解决方案: 遇到Memory limit (for query)超限报错说明是查询内存占用过多(实例总内存的70%)导致失败,这种情况下您需要垂直升配提高实...

报错提示Memory limit (for total) exceeded时,该如何处理? 问题原因:内存超过了server可使用的总内存。 处理方法:在EMR控制台ClickHouse服务的配置页面,单击server-config页签,单击新增配置项,新增参数max_server_memory_usage,该参数可以配置的最大值为机器物理内存大小 * max_server_memory_usage_to_ram_ratio。
